HeyReagent LinkedIn MCP

HeyReagent: a LinkedIn MCP server for your own account

HeyReagent is a hosted MCP server and API for your own LinkedIn account. You sign in once, connect LinkedIn, and give your AI app one address. From then on it can read your inbox, send messages and invitations, search people, and work with posts.

The MCP address: https://api.heyreagent.com/mcp

It is an address, so there is nothing to install or keep running, and it works in apps that live in a browser, such as Claude and ChatGPT on the web.

HeyReagent is not made by, affiliated with or endorsed by LinkedIn, and LinkedIn has not published an MCP server of its own. It is an independent service that acts on your own LinkedIn account, at your direction.

• The docs, with every action: https://heyreagent.com/docs?utm_source=github&utm_medium=readme
• The whole API as an OpenAPI 3.1 file: https://heyreagent.com/openapi.json

This repository holds the steps to connect an AI app, a plugin for Claude Code, and two n8n workflows. The server is hosted; its code is not here.

Before you connect

1. Sign in at heyreagent.com and connect your own LinkedIn account. It is free to start.
2. Claude and ChatGPT sign in to your account and need nothing more. For the others, make a key on the thread page: Menu, then Developers. It is shown once.

Connect your AI app

Claude

Signs in to your account. No key.

1. Open Customize, then Connectors.
2. Click + Add, then Add custom connector.
3. Type a name, paste the address, and click Continue.
4. Keep the sign-in settings Claude found, continue, and click Add. Sign in to HeyReagent when Claude asks.
5. In a chat, press + at the lower left, then Connectors, to switch it on.

ChatGPT

Signs in to your account. No key.

1. Open Settings, then Security and login, and turn on Developer mode.
2. Go to ChatGPT Plugins, select the plus button, type a name and a description, enter the address, and create the connection.
3. Sign in to HeyReagent when ChatGPT asks.
4. In a chat, choose Developer mode from the plus menu and select it.

Muse

Uses your key.

1. Send Muse the message below, as it is.
2. Muse answers with a card for the connector. Press Connect on it, then Continue, and paste your key in the form. The key goes there, not in the chat.
3. Muse asks whether it may share information with api.heyreagent.com. “Always allow this site” stops it asking before every request. “Allow once” allows the next one only.
4. Muse lists the actions and runs the check. Then ask it for what you want.

Create a custom connector called HeyReagent for my LinkedIn. It is a remote MCP server over streamable HTTP at https://api.heyreagent.com/mcp. Every request needs the header "Authorization: Bearer" followed by my key. Ask me for the key in your secure form, not in this chat. Then list its tools and run get_my_profile to check that it works.

Claude Code

Uses your key.

1. Run this in a terminal, with your own key where it says YOUR_KEY.

claude mcp add --transport http heyreagent https://api.heyreagent.com/mcp \
  --header "Authorization: Bearer YOUR_KEY"

Or install the plugin in this repository, which signs in to your account and needs no key. See The plugin.

Cursor

Uses your key.

1. Put this in .cursor/mcp.json in your project, or in ~/.cursor/mcp.json to have it everywhere, with your own key where it says YOUR_KEY.

{
  "mcpServers": {
    "heyreagent": {
      "url": "https://api.heyreagent.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_KEY"
      }
    }
  }
}

n8n

Uses your key.

1. Add an MCP Client Tool node to your agent.
2. Endpoint: the address above. Server Transport: HTTP Streamable.
3. Authentication: Bearer Auth, with your key.

The plugin

This repository is also a plugin for Claude Code, and for other apps that read the same layout, such as Grok Build. It holds two things:

• The MCP server heyreagent, a pointer to https://api.heyreagent.com/mcp (.mcp.json). Nothing is downloaded or run on your machine.
• The skill heyreagent (skills/heyreagent/SKILL.md): how to use the actions well. It tells the AI to ask you before anything is sent or changed on LinkedIn, to take ids from earlier answers, and what to do at a limit.

To install it in Claude Code, run these in a terminal:

claude plugin marketplace add linglistack/heyreagent-linkedin-mcp
claude plugin install heyreagent@heyreagent

Then start Claude Code, run /mcp, choose heyreagent, and sign in to HeyReagent in the browser window that opens.

Sign-in and network

The plugin connects to https://api.heyreagent.com, and the sign-in opens https://heyreagent.com in your browser. It reaches nothing else.

• https://api.heyreagent.com/mcp: the MCP server (Streamable HTTP).
• https://api.heyreagent.com/.well-known/oauth-protected-resource and /.well-known/oauth-authorization-server: where your app finds the sign-in.
• https://api.heyreagent.com/oauth/register, /oauth/authorize and /oauth/token: the sign-in itself, OAuth with PKCE. Your app registers itself; there is no client secret.
• https://heyreagent.com/signin: the page where you sign in and agree.

What it needs from you: a HeyReagent account with your own LinkedIn account connected. No key is stored in the plugin, and it has no hooks and no scripts.

What it can do

There are 97 actions (counted on 6 October 2026): Messages (27), Search (17), Posts (11), Jobs (10), Network (9), Profile (5), InMail (5), Recruiter (4), Insight (4), Account (4) and Sales Navigator (1). A few of them: who_is_waiting_on_me, list_conversations, send_message, send_invitation, search_people, get_recent_posts, comment_on_post.

Every action, with its inputs and what comes back.

The Sales Navigator, Recruiter and job-posting actions run on your own LinkedIn account and need that product on it.

n8n workflows

Two workflows that call the API from n8n's HTTP Request node. In n8n: the three dots at the top right, then Import from File (or Import from URL with the file's raw address). Each HTTP Request node needs a Bearer Auth credential holding your key; no key is written in the files.

File	What it does
n8n/find-people-and-invite.json	Searches LinkedIn people by plain words and a place, and sends each one a connection invitation with your note
n8n/invite-post-reactors.json	Takes the link of a LinkedIn post and sends a connection invitation to the people who reacted to it

Plans

Free, $0	Every Connect action. LinkedIn is disconnected after a while without use, so it is for working live.
Connect, $29.99 a month	The same actions with LinkedIn kept connected, so scheduled workflows run.
Agent, $499 a month	It runs LinkedIn for you: answers your inbox in your voice, follows up, and finds who to talk to. You approve what it sends.

Limits, and your LinkedIn account

Each LinkedIn account has a daily limit for each kind of action; an action past its limit is refused, with the time it resets. Reading your conversations is not limited. All the limits.

LinkedIn's User Agreement does not allow automated activity, and LinkedIn can limit or restrict an account that it decides is automated. Keep the numbers small, and spread what you do over the day.

Licence

The files in this repository (the plugin, the skill, the n8n workflows and this page) are under the MIT licence. The hosted service has its own terms and privacy policy.
